7797 Nyx Hemera Technologies has announced the installation tunnel lighting control system (TLACS) with Holophane's luminaires in the Queen-Creek tunnel in Arizona. The $3 million (£2,273,000) project is funded Department of Transportation in Arizona as part of ongoing efforts to upgrade the state road network’s efficiency and security.


The project involves removing the existing interior lighting, installing an LED lighting system and intelligent control system, replacing the exterior lighting at both ends of the tunnel, adapting the current electrical control building, and cleaning the tunnel’s walls and ceiling.

TLACS's intelligent control system dynamically adjusts lighting levels based on ambient brightness and outdoor weather conditions. The solution is designed to reduce both energy consumption and maintenance as well as improve the visibility of drivers commuting through the tunnel.

The 400-meter tunnel is located on road 60 at milepost 226, east of the town Superior.

    Camera technology a flexible and cost-effective option
    Perceptions of machine vision being an expensive solution are being challenged by developments in both core technologies and ancillaries. Here, Jason Barnes and David Crawford look at the latest developments in the sector. A notable aspect of machine vision is the flexibility it offers in terms of how and how much data is passed around a network. With smart cameras, processing capabilities at the front end mean that only that which is valid need be communicated back to a central processor of any descripti

    Arizona DOT upgrades camera system
    Arizona’s traffic operations centre was built more than twenty years ago; the first traffic camera was installed over Interstate10 in 1990. That’s all changed now thanks to a recent US$2.1 million upgrade of the camera system by Arizona Department of Transportation (ADOT) which replaced cables with fibre optic lines, so the cameras now show fresh images every ten seconds rather than every five minutes. The upgrade has also replaced the 32 video screens in the traffic operations centre, enabling staff to sca
